About 64mm across, made from the old vintage tooling. Silverware silverplated finish over brass, great detail....these make cool brooch tops! You will note that this plating shade is appreciably higher in price than many of our others. It is a true designer finish, worthy of the best work you can produce.....and, it just costs more. It is 99.9 percent fine silver, 3 mils thick...and many have agreed, it's worth the extra cost.Sold by the piece. NOTE: If you want or need an alternative to our silverware finish, purchase SILVER or GERMAN SILVER Gilder's Paste and apply it to the raw brass version of this piece, which we also carry and costs half this much. You can achieve a very nice silver color this way in very little time, and customize it to your liking, as well.
